The problem occurred again after few months. What I did to solve this problem is uninstall the driver and reinstall a new one.
1. Download the "Intel Wireless LAN Driver" from the ASUS support website.
https://rog.asus.com/laptops/rog-str...pdesk_download2. Right-click the [Windows] icon on the left of the taskbar, then click [Device Manager].
3. In the Device Manager, click [Network adapters]> [Intel Wireless-Ac 9560 160MHz]> [Driver] tab> [Uninstall device]> [Uninstall the driver software from this device]. Then, repeat this process with [Bluetooth]> [Intel(R) Wireless Bluetooth(R)].
4. After that, open the downloaded driver from step 1 and run it.
5. Restart your PC.
